Testing and modeling of sheet pile reinforced dikes on organic soils: Insights from the Eemdijk full-scale failure test

The Netherlands is inherently challenged by water, as a large part of the country lies below sea level and several major rivers in North-western Europe cross the country. The most prevalent form of protection from coastal and river floods in the Netherlands includes approximately 22,000 km of earthen dikes, of which 3800 km are primary flood...

Slope failure simulations with MPM

The simulation of slope failures, including both failure initiation and development, has been modelled using the material point method (MPM). Numerical case studies involving various slope angles, heterogeneity and rainfall infiltration are presented. It is demonstrated that, by utilising a constitutive model which encompasses, in a...

Slope Failure Simulations with MPM

The simulation of slope failures, including both failure initiation and development, has been modelled using the material point method. By utilising a constitutive model which encompasses, in a simplified manner, both pre- and post-failure behaviour, the majority of types of geotechnical slope failure can be observed in the simulations. This is...

Uncertainty Evaluation in Slope Failure using Centrifuge Model Tests

Strong nonlinear behavior such as slope failure involves large uncertainties. Even if we conduct model tests on slope failure under the same test conditions, we cannot reproduce the same results although the linear behavior can be reproduced with relative ease. This kind of uncertainties is well known as “aleatory uncertainty” and they should be...

Uncertainty in centrifuge test of slope failure and its simulation by MPS method

We sometimes encounter a case in which very small change of computation or experiment condition causes the significant difference in response when strong nonlinearity is involved. Slope failure simulation due to gravity by MPS method is performed to examine feature of uncertainty. The simulation results show that the output uncertainty is...

Assessment of Risks of Regional Shallow Slope Failures

Shallow slope failures are one of the most frequent geological hazards in mountainous areas, which pose great danger to people and properties in affected areas. This paper presents a cell-based platform for quantitative risk assessment for shallow slope failures at a regional scale. There are five components in this platform; namely, a digital...
